Evening sky in APRIL 2015
Sirius, the brightest star in the night sky, appears in Canis Major (Big Dog), high in
the north-western sky. Below it and slightly to the east in Canis Minor (Little Dog), we
find the binary star, Procyon. It is the 8th brightest star in the night sky and lies at a
distance of 11.4 light years, making it one of our closest stellar neighbours. One of
the two stars in the system is a white dwarf star. Its presence may cause unstable
orbits in the habitable zone of the system and therefore the existence of planets
supporting life is unlikely. Procyon also emits more of its light in the ultraviolet
spectrum, which is harmful to life as we know it.
Planet Venus, the bright "Evening Star" in the west, moves from Aries (Ram) into
Taurus (Bull) by mid-month. Planet Jupiter is to the north in the constellation of
Cancer (Crab). Its four biggest moons can be seen with binoculars. Watch their
configuration on either side of the planet change from one night to the next as they
orbit quite quickly around Jupiter. Planet Saturn is in Scorpius (Scorpion) rising in the
east.
The Moon is in the evening sky until 7 April and again from 19 April.
The Autumn equinox is on 21 March.
